alternative energy sources
Alternative energy is a term used to refer to forms of energy that are naturally obtained from the environment and from sources that be replenished naturally. These include solar energy, wind energy, geothermal energy, hydropower and biomass.
Sources of Renewable Energy:
There five(5) major sources of alternative energy
Solar energy is radiant light and heat from the sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy including solar water heating, and solar architecture.
Wind energy is mostly to use of wind turbines to generate electricity. Wind power is a popular, sustainable, renewable energy source that has a smaller impact on the environment than burning fossil fuel. Wind farm consist of many individual wind turbines, which are connected to the electric power transmission network.
Geothermal power is electrical power generated from geothermal energy. Technologies include dry steam power stations, flash steam power stations, and binary cycle power stations.
Hydro power is the use of falling or fast-running water to produce electricity or to power machine. Hydro-power is an attractive alternative energy to fossil fuel and it provides a relatively constant source of power.
Biomass energy is a plant-based material used as fossil to produce heat or electricity. Examples are wood and wood residues, energy crops, agricultural residues, and waste from industry, farm and households.
Advantages of Alternative Energy
-Less maintenance value as most sources entail few or no moving parts, hence, less mechanical damage.
-They are economical and may cut prices spent on fossil fuel
–Renewable energy sources don’t deplete. Therefore, these have a higher prospect for the longer term
Disadvantages of Alternative Energy
-The electricity generation capability remains not massive enough
-Renewable energy may be unreliable
-Requires a large direct capital
-Takes a lot of spaces to install
-Expensive storage prices
-Not always a comercially-viable option
